To aZZ whom it may concern:

Be it known that l, Gnonon F. MoGILL, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Change- Maker; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

The invention relates to an improved type of a change maker having a plurality of coin tubes for holding coins of different denominations, each ofsaid tubes having associated therewith a lever actuated arm pro vided with a counterweighted ejector adapted to eject a coin and cause said coin to operate a counter-weighted means to retract a slidable coin support to permit discharge of thecoin, said means adapted to act automatically to return the coin support into normal position.

It is an object of this invention to provide a change maker wherein the friction between the ejecting mechanism parts is practically ne ligible.

Tt is'also an object of the invention to provide a change maker with a gravityacting ejector, and a gravity controlled retractable coin stack support.

Another object of the invention is to provide a coin tube with a movable gravity controlled coin support adapted during the e ection of a coin to support the rear portion of a coin until the front portion. has been moved clear of stationary supports to permit the coin to drop through a discharge openmg.

A further object of the invention is to provide a coin holder with a pivoted gravity acting ejector adapted during an ejecting operation to engage the lowermost coin ofa stack of coins and eject the same and then tip slightly to permit the ejecting tip to frictionally slide outwardly underneath the remaining lowermost coin until said coin is cleared to permit the ejecting tip of the ejector to be elevated by gravity into normal ejecting position.

It is an important object of this invention to construct a change maker wherein the coin to be ejected normally rests on comparatively small supporting surfaces to reduce the fries wardly with the open tional resistance to a minimum during an ejecting operation of a coin.

Gther and further important objects of this invention willbe apparent from the disclosures in the specification and drawings.

As shown on the drawings:

The change maker comprises a box or casing comprising a bottom plate 1, side plates 2 and 3, a removable back plate 4;, a lower front plate 5, an upper inclined front plate 6 and a rearwardly inclined table plate 7. The upper end of thecasing be tween the upper inclined plate 6 and the back plate 4 is closed by a suitable top to prevent access to the interior of the casing. The table plate 7, extends rearwardly and abuts the back plate 4. The casing is supported on legs 8. Formed in the lower rear corner of the side plate 2, is an opening 9. Secured to the inner surface of the table plate 7, is an inclined trough or chute 10, which slants downwardly and rearward starting from the side wall 35, to permit the lower or discharge end 11, thereof to project through the opening 9, and curve rear,- end thereof disposed above a coin receiver or cup 12, mounted at the rear ofthe casing.

Mounted on the front surface of the in clined upper front plate 6', is a plate'ii i, to k which is rigidly secured by rivets 14, or other suitable means a plurality oi": adjacently disposed parallel inclined coin tubes 15, of different sizes for holding stacks of coins 16, of diiterent denominations. Each coin tube 15, is cut away at the lower margin to afford an opening 1?. Provided in the table plate 7, below each of the coin tubes 15, is a round discharge opening 18, a portion of which is positioned to extend to the front oi the plate 6, while the rest of said opening is positioned to the rear of the plate 6, as clearlyshown in Fig. 3. Each discharge opening 18, is provided with a front guide slot 19, and a rear guide slot 23, formed in the table plate 7, and diametrically alined with one another. Each coin tube 15, has the lower side margins bent inwardly to afford stationary coin supporting flanges 21, the coin supporting surfaces of which are comparatively small for the purpose of minimizing the friction. between a coin and said supporting flanges when a coin is ejected. The coins 16, are deposited in the top oi a coin tube and drop to the bottom of the tube with the lowermost coin resting on the supporting flanges 21, and in a plane with the outlet opening 17. Angle stops 22, are secured on the table plate 7, to one side of the front guide slots 19, for the purpose of preventing outward movement of the lowermost coins in the coin tubes.

Since the coin ejecting mechanisms for each of the coin tubes are alike the description will be confined to one of said mechanisms. Securely mounted on the plate 6, behind the coin tube'15, is an angle bracket or lug 23, to which is pivotally connected by a pivot pin 2a, the angle portion of a bellcrank comprisin a short arm 25, and a long arm 26, integrally formed at an angle with said short arm. The lower end of the bellcrank arm 26, projects through a slot 27, formed in the front end or a slidable guide plate 23, and through the discharge opening 18. Formed on the end of the short bell-crank arm 25, is a weight 29, adapted to act as a means for normally holding the slide plate 28, in its forward position to permit the rear portion or" the lowermost coin 16, in the tube 15, to rest on a movable coin supporting tip 30, integrally formed on the front end of the slidable guide Jlate 28. Secured on the rear portion of the table plate 7, are a pair of guide strips 31, bent to afford guide grooves for the slidable plate 28.

The ejecting mechanism for each coin tube is mounted in the lower chamber of the casing and comprises a pair of spaced upright apertured lugs 32, which are integrally formed or rigidly secured on the inner surface near the front margin of the casing bottom plate 1. Supported by the lugs 32, is apin 33, on which is pivotally mounted the angled portion of a bellcrank embracing an upwardly projecting long arm 3 and a short arm 35. The upper end of the long arm 34, is slotted to receive a gravity acting ejector 36, supported on a pivot pin 37. One end of the ejector is pointed or tapered to form an ejecting tip which normally projects upwardly through the front slot 19 in the table plate '2'. The other end of the ector is provided with a weight 38, for normally holding the ejecting tip in its elevated position. Secured on the casing bottom. l, is one end oi" a spring 39,.

the other end of which is secured to the arm 35, normally hold said arm elevated, so that the free end thereof will hold an operating lever 40, in raised position as shown in full lines in 3. The lever LO, has the inner end thereof pivotally connected to pin 4L1, supported by lugs d2, secured on the casing bottom plate 1, to the of the front lugs 32. The other or free end of the lever ll), projects outwardly through a vertical slot a l in the arm an. through a slot 45 provided for the purpose in thelower front wall 5, the casing. button or lrey 4 .3, is mounted on the outer end of the lever ll), and said button is provided with a numeral to indicate the denomination of the coins in the coin tube 15. The operation is as follows:

Coins 01? different denominations, such as with a coin tube, is held in its forward po-' sition as shown in Fig. 3, with the suppor ing tip 30, projecting into the coin tube to engage underneath the rear portion of the lowermost coin in the tube. The plate 28, is held in place by the bell-crank member 25-26, the weight 29, acting to hold the lower end of thearm 29, in itsflorward position. The normal position of the ejector 36 18 shown in full lines in F1 3. The,

spring 39, cts to hold the bell-crank arm 35, and the lever 40, in their elevated position.

Normally the tip of the ejector 36, projects upwardly through the table plate slot 19, in front of the lowermost coin 16. To eject the lowermost coin from underneath a stack of coins in a coin tube, the button 43, is depressed, thereby forcing the lever 40, to swing downwardly into the dotted line position of Fig. 3. Downward movement of the lever acts to depress the short bellcrank arm 35, against the action of the spring 39. As the arm 35, swings downwardly the long arm 34, is simultaneously swung rearwardly, thus moving the ejectand the movable supportingv thus forced to slide rearwardly on the sta tionary supporting flanges 21.. The supporting tip 3). and the plate 28, move rearwardly with the 00111, at the same time pulling the lower end of the long bell-cranlr arm 26, rearwardly and elevating the weighted arm 25. The rear portion of the coin is supported during its movement by the supporting tip 30, until the coin is brought into a position to register with the discharge opening 18, in the table plate 7. The coin is then permitted to drop through the opening 18, into the inclined chute 10. The deposited coin falls or slides downwardly by gravity through the chute 10, and is deposited into the receiving cup 12.

Simultaneously with the discharge of a coin, the weight 29, acts automatically to force the plate 28, forwardly to again position the supporting tip 30, underneath the stack of coins remaining in the chute 15. With the release of the button 43, the compressed spring 39, acts automatically to elerate the arm 35 and the lever 40, to normal position. Upward movement or" the arm causes the arm 34:, to move outwardly from the dotted line position of Fig. 3, into the full line position. The ejector 86, being pivoted in the upper end of the arm 84, is adapted to have the upper end or tip swung downwardly so that said ejector tip can slide outwardly underneath the lower coin in the coin tube. As soon as the ejector tip has cleared the front of the lower coin the ejector weight 38, acts automatically to again raise the tip end of'the ejector into normal position, ready to engage the next coin.

Attention is directed to the fact that the ejecting mechanism is very easily operated, partly due to the fact that the supporting surfaces of the stationary coin supporting flanges 21, are smooth and comparatively small. The return of the movable supporting tip 30 to normal position is substantially simultaneous with the ejection of a coin.

If desired the movable support 30, may be integrally formed or secured on the lower end of the long bell-crank arm 26, and the guides 31. and the slidable plate 28, may be omitted.

I am aware that numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.
